My 1997 f250 lost the block heater and destroyed the engine, I have an opportunity to get ahold of a 1989 460 with low miles however the wreckers say the engines differ and are not interchangable. Does any one know what is different and is this true as they sure look the same

Emissions. Or for a better term Computer tech. In 1995 OBD came out with a raft of emissions components and an older engine (pre 95) won't be compatible to run on a newer wiring harness let alone pass current emission standards.

The blocks are the same, but to utilize the older engine you'll have to use the old wiring harness and computer (or lack there of), leaving your newer truck with multiple engine lights and the like to deal with. In some states it's required that no engine lights be on in order to pass safety inspection either, which is why some shops will tell you flat out to stay away.
